This invention relates to a new and useful improvement in a mechanical movement designed especially for, use n connect on with the motor disclosed in my copendlng application filed April-7, 1919, Serial Numcation is a division. 7 v

In the drawings, I have shown my improved mechanical movement as adapted for usein connection with a drill in which air or steam maybe used as thamotive. power. The purpose of the present nvention is to convert the reciprocating movement of the piston of the engineor motor into a rotary 1 In the drawings, 1 indicatesaflanged cylinder, preferablyin the form of a casting having a valve chamber 2 located to oneside Fig. 5 is a sectional viewfon line 55 of a lazy man. ber 290.800, and of which the present appl Specification otLettci' 's Patent. 1921, Original application filed April 7, 1919, Serial N0. 290,800.

Y 10 is a hollow: piston' rod mounted upon the shaft which shaft 6 may be'designated as the drlving shaft, the sleeve or hollow piston rod 10' being designed'to slide longitudinally upon the driving shaft 6'while the 2 flatter rotates.

in a Suitablemountin'g, 1 pr eferably by a threaded connection, to the forward end of the hollow piston rod 10; saidjpiston'hea'd having the .usual packing rings 12. The -p1ston comprising the head and hollow rod- 11 is a piston head 'se'cured 2.0 are intended to reciprocate within cy1- inder l and passing through the-packing mountedfin the rear cylinder head '8, t P t n rod 10 extends. into a chamb formed by a cylinder 1-3.. secured to :the' rear cyl nder head 8.. This cylinder 13 is'closed at ts rear endby'means of aihe'adltgand capped sleevelh-havirig handles 16 by which the drill'maybe fed, as when boring through metal and the) point a at the -.rear:. end of the cap piece is placed under what 'i's'known as The operation of, this feeding-mechanism isbriefly this the cappiece 15is unscrewed gradually as the: drill is being fed. forward and the 'point at therear' end thereofen- .is exteriorly threaded to accommodat'e a gaging some station'arysupport will ena'ble on the-*dril-l and-feed ifs-forward. 1 a: 1-7v indicates a-rod'mbunted-ijn the opening through the driving-shaft 6-,{sai'd rodhavr the operator to L exertthe necessary pressure ing a round ,headseated in-a rece ss in 'the" head 14C and. havingfits forward' endafranged in such relation tothesocket which receives the drill shank indicated by dotted lines X that, 'when the drill shank isgh'o'me the rod17 will be slightly displacedj rear 'wardly, and in the eventthat the -drill. "shank gets stuck in drivingshaft 6 ;;,the s1eeye;.=l5

may be turned down to forcethe drillshank forwardly and loosen it. Of course, the sleeve 15, where the drill is operated manually, would be turned slightly back to permit the rear movement of the shaft 17 when the drill shank is inserted in the position to accomplish the above. The rear end 'of'the main driving "shaft 6 preferably engages Y the head 14 through'the medium of theballbearing to take'up theend thrust and re- 'duce friction.

. The? cylinder 13,. constitutes an oil-chamberypreferably provided with alubricant j, to give a splash feed, and, as shown in Figs. 5.

2' and 4,;is provided .with oppositely disposed guideways 13 in which is reciprocally mounted a cross-head 19. This cross-head has a .medial inwardly extending non-circu- 1 lar flange (octagonal, as shown in'Fig; 5)

in: which is slidingly mounted a double ratchet faced :nut 20,:' shown in. Fig.

8,- which nut is, provided with an openingwthrough which the fdriving shaft 6 passes. The cross-head 19 has flanges extending lIL OPPOSltG directions from the medial inwardly extendlng flange ust mentionejd,= in the forward one of which is threaded an offset flanged on the'rear end of the piston radio, while in the rear flange isthreaded a cap-piece 21. This cap piece 21 and-"the offset fiangeof the piston rod ju'st referredlto form seats or hangers for clutch members 22, see Fig. l, and Fig.7,

7 the inwardly disposed faces of which are .with-the' double-faced ratchet nut 20. These provided? with ratchet teeth to c'oeperate clutch members 22are likewise strung upon the-maindriving shaft- 6. The' inner faces ;of' ratchet member 22are provided with feathers or-splines 23 oppositelypitched so as top-engage 'and cooperate with spiral 'groovesfiiin the main driving shaft 6, and

. 'these' clutch members are free to rotate within-"their respective chambers and they also have a slight movementjlongitudinally on shaft 6 isuflicient 'to cleanthe "teeth when they are disengaged from thej double-faced ratchet'nut. This double faced ratchet nut is held" against 'longitudinal' movement, by

"the .piston'rod' 10; and the cap piece 21 and, Of'C0\1!S'B, 'iSI held against rotation within the s 19 y h no'n-circ'ular conto'ur'of its seat.

- mThg operationl' f 'it te P i Sabove scribed infconverting the reciprocating motion ofthe piston; and'its rod 10 to a rotary motion isbriefiyas follows: Assuming that the piston receivesair orsteam at. one end -whilethe other end is open to exhaust and vice versaandthat itis caused to reciproca'te say at the rate of four or five hundred s'trolresper minute, the ciidsshead 19 being carried 'jwithit will also carry the'clutch members 22;-wi thinltheir respective housings j the momentum of {the piston atthe end of hers idly,- spin with .the. shaft.

clutch members are so related to the doublefaced ratchet nut that vthereis just sufficient each half stroke will cause these clutch members to alternately become engaged with and disengaged from the double faced ratchetythe engaged clutch member being rendered non-rotatable at the time ofrits' engagement with the double faced ratchet will, by virtue of the inwardy extending verse stroke of thepiston, the driving shaft 'c. v pitched in CllIGCtlQIl whereby on the re- 6 through its second or oppositely pitched] groove, will be driven in the same direction as that first above described with res ect to the first'mentioned clutch member. he purpose of providing the clutch members andthe double faced ratchet with ratchet 1 teeth is to enable the main driving shaft 6 to continue its rotation in the event that the pistonceases its operations at anytime, as when the power is cut off. 'Assuming that the mainshaft 6. extended forwardly and was'provided with a balance wheellwhich by its momentum, wouldcontinue the rotation' of the maiashaa after power-tad been shutoff from the engine, the directionof rotation would be such that the clutch member in driving engagement-therewith. would be instantly disengaged and both clutch mem- These two clearance between the teethto 'enablefthem to idly rotate with the shaft.

Where the motor is used as La manually 25 and 26, thellatter offwhichmaybe in the form of a pipe having any suitable valve com-01am connected to asour'ce of air or steam supply. .The. pipe 26 communicates operable drill, the casting l is providediwitli lugs 1 (Fig. 2) in which are fitted handles with the valve chamber 2 infwhich'is located t a valve the detailsof which are shown in companion application referredto and form no part of this present invention.
